Is Surf Wallet safe?

Medium risk

Surf Wallet embeds a live MoonPay signing secret and uses it to build checkout URLs for wallet addresses.

When a user starts the MoonPay buy flow, Surf Wallet builds a MoonPay checkout URL that includes the user's wallet address and a signature. The signing secret is recoverable from the shipped JavaScript bundle as byte values, so the extension uses a live vendor credential client-side.
